.SPECIFICAIION formingpart of Letters Patent No. 539,339, dated May14,1895. 7

Application filed June 4, 1894. Serial No. 513,488. (No model.)

To aZZ whom it may concern:

Be it known that 1, HENRY BREITENSTEIN, residing at Laramie, in thecounty of Albany and State of Wyoming, have invented a new and ImprovedLocomotive Bell-Ringer, of which the following is a specification.

My invention relates to steam operated bell ringing devices, and itprimarily has for its object to provide a simple, and inexpensivemechanism easily operated and very effective for the desired purpose.

It has also for its object to provide a bell ringing mechanism soarranged that the steam will serve to operate the plunger or piston inone direction, only, it being operated in the reverse direction by theweight of the bell.

With other objects in view which hereinafter will appear the inventionconsists in such novel features of construction and detail combinationof parts, such as will be first described in detail and then bespecifically pointed out in the appended claims, reference being had tothe accompanying drawings, in which- Figure 1 is a vertical section ofthe bellringer on the line X X, Fig. 3., Fig. 2 is a halfelevation andhalf-section'on the line Y Y, Fig. 3. Fig. 3 is a transverse section onthe line Z Z, Fig. 1, with the piston removed. Fig. 4 is a sideelevation of the bell and ringer.

The cylinder A, contains the piston B, socured or cast together with thepiston rod 0,

connected with the main driving shaft of the bell yoke, in the usualmanner.

The valve chamber D contains the Valve piston E'past together with thevalve E in valve chamber D.

The valve E, operates over the inlet port e,

. in Valve chamber D, and over the exhaust port f, leading to theoutside.

From the upper end of cylinder A, there leads a port g, to the exhaustport f, to avoid the forming of pressure above piston B, on its upwardstroke. Just below the piston B, after it has reached its extremeuppermost position, there leads a port h, from cylinder A, to valvechamber D.

Through the center of the valve E, a port 2', connects the cylinder A,with the inlet port 6, when the valve is forced to its lowermost travelby the piston B, as shown in Fig. 1, when connected in the usual mannerwith the main driving shaft of the bell yoke as shown in Fig. 4, therebyadmitting the motive agent into the cylinder A, through the port 2',in-valve E, which forces the piston B, upward until it passes the porth, in cylinder A, as shown in Fig. 2, when the live motive agent ispermitted to enter the valve chamber D through the port it. A port It,from valve chamber D, into exhaust portf, prevents the accumulation ofpressure above the valve piston E'. The valve piston E being of a largerdiameter than valve E, it is" forced upward to its extreme travel,closing the inlet port e, and opening the exhaust port j, as shown inFig. 2, when the piston B, is free to be moved downwar'd by the weightof the bell. When the bottom part of the piston B, has reached the valveE, and before it has quite completed its downward stroke, the upper edgeof piston B, opens port h, allowing the motive agent beneath the valvepiston D to escape out of the top of cylinder A, through the port g,and.

into the exhaust port f, leading to the outside, permitting theoperationto be repeated.

I claim as new and desire to secure byLet ters ]?atent--v 1. Alocomotive bell ringing mechanism comprising a cylinder having inlet andexhaust ports, a piston operating therein having its stem connected withthe bell ringing member, a shifting valve having a port dischargingagainst the operating piston said port being adapted to be alternatelybrought in register with the inlet and exhaust ports of the cylinder,the said cylinder having a supplemental port opening into the cylinderand discharging at a point under the shifting Valve and so arranged thatwhen the bell operating piston reaches its uppermost point of stroke, the air or steam under it will pass down under. the shifting valve, andshift it to an exhaust po* sition, substantially as shown and described.

2. An improved bell ringing mechanism comprising a cylinder having anupper and lower chamber and inlet and exhaust ports below the upperchamber, a bell operating pis ton held to travel in the upper chamber, a

shifting valve having its stem projecting into ber, provided vwithlaterals adapted to beat-- ternately shifted into register with theinlet and exhaust ports, a supplemental port or channel opening into theupper chamber at a point under the bell operating piston when at theuppermost stroke arranged to discharge under the piston of the shiftingvalve, and a bleeding oft port in the top of the upper chamber allarranged substantially as and for the purposes described.

3. As an improvement in bell ringing devices, a cylinder having an upperand lower chamber connected by a contracted or throat portion said lowerchamber having the inlet and exhaust ports communicating therewith,

a shifting valve operating in the lower chamher, having a stem fittingin the said throat portion, said stem having afeed port opening into theupper chamber and adapted to be alternately moved into register with theinlet and exhaust ports, and the port h connecting the upper and lowerchambers substantially in the manner shown and for the purposesdescribed.

4. The combination with, the cylinder A, having an upper and a. lowerchamber, connected by a contracted valve space D, said lower chamberhaving the inlet and exhaust ports connected therewith, and a port 70connected with the exhaust port, of the piston 13 operating in the upperchamber, the valve E operating in the space D, having a head member Eoperating in the lower chamber said HENRY BREI'IENSTEIN.
